Really different questions with different answers.

If it were just for my own care-free leisure and benefit, I would probably go to school again and try some other academic path in math, physics or history. Or rekindle my CS study and do a phd - so many different interesting topics.

In the real world, as a parent with a huge mortgage? Pretty much anything. Janitorial work, insurance agent, landscaping, whatever.
